Add a link to each class to register

looking to put a direct link i can use to a certain class that i can send to the parent to book right away instead of giving them the login page link so it brings them right there to that specific class.

Example:i have a tiktok and flip flips camp that i will be promoting on my website and when you click the flyer i want it to take them to that exact camp thats on DSP (if and when they are logged in)
